WILBER D. FORSYTH AND ENOS T. BELL, OF .PITTSBURGH PENNSYLVANIA,

ASSIGNORS TO THE UNION BOILER TUBE CLEANER COMPANY, OF PITTS- BURG,PENNSYLVANIA, A CORPORATION OF PENNSYLVANIA.

BOILERu-TUBYE CLEANER.

srncrrrcnrion forming part of Letters Patent No. 698,193, dated April22, 1902.` Application led January 17, 1899. Serial No. 702,472. (Nomodel.)

' T0 all whom/ t may concern:

Be it known that we, WILBER D. FonsYrH and ENOS T. BELL, citizens of theUnited States, and .residents yof Pittsburg, in the 5 county ofAllegheny and State OfPennsylvania, have invented certain new and usefulImprovements in Boiler-Tube Cleaners; and

we do declare thefollowing to be a full, clear,

and exact description of the invention, such :o as willenable othersskilled in the art to which it appertains to make and use the same,reference being had; to the accompanying drawings, and to letters freference marked thereon, which form a part of this specification.

r Figure l of the drawings isa representation of a perspective view,partly broken away',

showing the invention as in application. Fig.

' zo end elevation of same. Fig. 4 is a detail view illustrating thestud C3 of the bracket. i

This invention has vrelation todevices for operating boiler-tubecleaners and is designed to provide means whereby the feed-rod of a z 5boiler-tubecleaner may beY driven by a direct motor connectionitherewithwhile capable of being readily moved fromonetube of a'boiler tofanother.

With this object in View the invention con- 3o sists inthe novelconstruction and combination of parts, allfas hereinafter described,`andpointed outin the appended claims.

Referring to thel accompanying drawings, the letter A designatesthefeed-rod of a boilertube cleaner, (indicated at B,) said'rod inoperation being rotated at a highl rate of speed, while at the same timeit is moved longitudinally to carry the cleaner through the tube beingcleaned.

C designates a bracket or casting which is mounted to slide laterallyupon a fianged guide rail or bar D, being actuated by a feedscrew D.Said screw has a bearingat each end portion in lugs d of the bar or railD and engages a nut C of the casting C. It is provided at each endwithan operating-handle D2. The slide portion C2, which engages the bar orrail D, is made in two sections, which are bolted or clamped togetherand seat between themaJ depending cylindrical stud or 5o stem C3 of thebracket proper atthe forward portion of the bracket. By loosening thefbolts which clamp this stud or stem the motor and feed-rod may bereadily turned there- -on to enable the feed-rod to yenter a tube ofVthe boiler which may have become warped at pose of moving the bar inthese guides windlasses F and rope connections F are shown.

We do not, however, confine ourselves to any iparticular means forsupporting and moving the Said bar 0r rail, as various devices may beemployed for that purpose. The arrangement shown and described has,however,

proved very satisfactory and convenient for 7o' Vthe purpose.

G designates a motor or engine, the base portion G of whose casing issecurely bolted or otherwise secured to the bracket or casting C. Thismotor or engine may be of any suitable rotary type, operated by steam,water, electricity, or other suitable power. A steam-motor is, however,preferred, as it may be readily coupled up to the steam-generators ofthe plant in which'the apparatus is being 8o used. The shaft Gr2 of themotor is journaled at one end in bearings H, mounted in avertical arm ofthe bracket or casting,l and has ixed thereto a spur gear-wheel I. Thebracket vorcasting also has a horizontal forWardly-eX- tending arm C4,provided with a transverselywhich it is keyed atj', and is preventedfrom such removal by the clamp J2.

L designates a casing which surrounds the gear-wheels I and K, beingsecured to the boxing enlargement above referred to at the top andbottom thereof.

In operation the bracket or casting C is adjusted on thebar or rail D tobring the feedrod into alinement with the particular tube ot' the boilerwhich is to be cleaned, the said bar or rail D being also adjustedvertically to bring it into proper relation to the hori-V zontal seriesof tubes in which such tube is situated. The cleaner is introduced intothe tube an d the motor is started, thereby through the gears I and Krotating the feed-rod. As the operation continues the said rod is pushedlongitudinally into the tube, its spline @sliding in the keyway ot' thesleeve J. A small stream of water should be kept flowing into the tubeduring the operation to prevent heating and to remove the loosened anddisintegrated scale. As soon as one tube is completely cleaned thebracket or casting C is moved laterally on thebar or rail D into properposition for the next tube in the same horizontal row or series, andwhen that row or series is cleaned the bar or rail is raised or loweredon its guides to bring the devices into proper position for the next roworseries.

Having thus described our invention, what we claim as new, and desire tosecure by Letters Patent, is-

l. In mechanism ofthe class described, the combination ot' thetransverse bar or rail, means for vertically adjusting the same, thelaterally-adjustable slide carried by said bar or rail, the brackethaving the cylindrical downward extension and the upward extension, theclamp upon said slide engaging said downward extension, the outer rotarysleeve journaled in said bracket, the inner concentric endwiSe-removablesleeve rotatably connected to said first-named sleeve, means forsecuring said innersleeve from endwise movements,the feed-rod engagingsaid inner sleeve, the rotary engine carried by said bracket, the shaftof said engine, having a journal-bearing in said upward extension, andcarrying a gear-wheel meshing with the gear-wheel upon said outersleeve, substantially as speciiied.

2. In mechanism of the class described, the combination of thetransverse bar or rail, means for vertically adjusting the same, the

laterally-adjustable slide carried by said bar or rail, the bracket uponsaid slide, having a transversely split cylindrical boxing, and thesemicircular enlargement connecting the sections ol" said boxing, therotary sleeve journaled at opposite ends thereofin said boxing, thegear-wheel mounted centrally ot said sleeve in the space separating thesections of said boxing and partly inclosed by said enlargement,thefeed-rod engaging said inner sleeve, the rotary engine carried bysaid bracket., the shaft of said engine carrying a gear-wheel meshingwith said first-named gear-wheel, and the guard-strip secured at one endthereof to the upper portion of said enlargement, carriedV around thegear-wheel upon the engine-shaft, thence partly around the gear-wheelupon said sleeve, and secured to the lower portion of said enlargement,substantially as specified.

3. In mechanism of the class described, a transverse bar or rail, alaterally-adjustable slide mounted upon said bar or rail, a bracket uponsaid slide,and having a cylindrical downward extension at one endportion thereof, clamped to said slide and revoluble therein to allowsaid bracket to be turned, a rotary sleeve having bearings in theopposite end portion of said bracket, the intermediate portion of saidbracket resting and turning upon the upper surface of said slide, afeed-rod actuated by said sleeve, and a rotary engine mounted upon saidbracket, and geared to said sleeve, substantially as specified.

4. In mechanism of the class described, a transverse bar or rail, alaterally-adjustable slide carried by said bar or rail, a bracket uponsaid slide having a boxing at one end portion thereof, an outer rotarysleeve journaled in said boxing, an inner endwise-removable sleeverotatably engaged by said first-named sleeve, a clamp upon said bracketand engaging the outer end of said inner sleeve, a feed-rod actuated bysaid inner sleeve, anda rotary engine carried by said bracket, andgeared to said outersleeve, substantially as specified.

In testimony whereof we affix our signatures in presence of twowitnesses.
